The bolts are measured in the free state and sizes noted, then in our case the 4 bolts were progressively tightened to the specified stretch, (not fully tighten 1 bolt then the others) a somewhat tedious operation particularly if you have 18 rods to tighten. Best with 3 men, one with the stretch gauge, note pad and pencil while the other 2 provided the grunt.
